[Also in Division F2] Partitions are formed from horizontallyspaced vertical frameworks comprising interconnected horizontal, e.g. 103a, and vertical, e.g. 101a, framing members, clad with facing panels, e.g. 104, the vertical members being forced upwards when in place into a position where they are wedged between the floor and the ceiling. As shown in Fig. 1, adjacent vertical members 101a and 101b are interconnected at each end, and forced upwards by wedge-shaped members 123a and 123b which are screwed together by a rod 125 having oppositely threaded ends. The panels may be hooked on to the vertical members via a two-part support bracket (Fig. 5, not shown), the lower part 128 of which sits in an elongate channel in member 101a, and is compressed and wedged in position by the upper hooked part 127, or they may be set directly into other elongate channels in the framing members (Fig. 4, not shown) with a protective resilient edge beading 129. The horizontal and vertical framing members are interconnected by a two-part wedging connector (Fig. 3, not shown) which is forced along the appropriate elongate channel in a horizontal frame member until it expands and grips the vertical framing member. Panel 105 has rebated horizontal edges for connection to a plinth panel 106, and a cornice 107. A sound-absorbing panel 108 is arranged between the facing panels.

Title: Improvements in or relating to open hearth furnace
IPC: F27B3/26
Filed: 1952-04-04
Abstract: 769,513. Open hearth furnaces. INLAND STEEL CO. April 4, 1952 [July 6, 1951], No. 19517/55. Divided out of 767,933. Classes 51 (1) and 51 (2). In an open hearth furnace having a burner and a single vertical air uptake at each end, air from the regenerators passes via a horizontal fantail passage 29 and a slag pocket 30 into the uptake 25 formed with a narrowed venturi section, said uptake 25 being defined by an end wall 17, a chill-box section 21 and wing walls 31 and 32. The wing walls are formed with lower curved sections 33 and 34 forming the venturi-section with the longitudinally and upwardly sloping chill-box wall 49, and with outwardly flaring wall sections 35 and 36 leading to upper vertical sections 37, 38 spaced apart by the full width of the furnace between the buckstays 18, 19. Burner ports at each end of the furnace are shown at 26, Fig. 2. The ratio of the length of the fantail passage 29 to that of the slag pocket 30 is at least 1 to 2.34. With this construction, the air supply is centrally and uniformly delivered, enabling higher fuel consumptions to be efficiently obtained, and the chill-box section 21 being closer to the back wall, the capacity of the hearth 12 can also be increased for a given furnace.

Abstract: 672,949. Discharge tubes. WEIGHTON, D., and PYE, Ltd. Sept. 28, 1950 [July 26, 1949], No. 19629/49. Class 39 (i). [Also in Group XL (b)] A gas discharge tube T for reconstituting successive complete lines of a television image comprises a plurality of electrodes E connected to respective spaced points along a delay line to which the television picture signal is applied via terminal A, and a discharge electrode D to which a triggering pulse synchronized with the line synchronizing pulses is applied via terminal B. The picture signal produces a spatially distributed positive charge pattern along the delay line, and this is discharged at the end of each line by the application of a negative pulse to terminal B, thus producing a glow pattern corresponding to one line of the television picture. In a modification, Fig. 3, the delay line, comprising a coil wound upon a copper former, is mounted within the discharge tube, the discharge in this case occurring from successive turns of the delay line itself.

The devolatilized mixture is stable in the absence of moisture, but can be cured by addition of further organotrialkoxysilane and an organotitanate catalyst and exposure to moisture at room temperature. In Example 1 a methyldimethoxysiloxy - terminated polydimethylsiloxane is mixed with water, hexamethyldisilazane, Al 2 O 3  and methyltrimethoxysilane, and the mixture heated to 100 C. under 10-20 mm. Hg. The devolatilized mixture is mixed with methyltrimethoxysilane, a small amount of reinforcing silica and butyl titanate to give an RTV composition which cures in moist air. In Example 2 the silane is omitted from the initial mixture, and in Examples 4 and 5C the oxide is ZrO 2  or MgO. In Examples 5A and 5B the mixture is varied by using methyldiethoxysiloxy-terminated polymethylphenylsiloxane and diisopropoxytrifluoropropylsiloxyterminated polymethyltrifluoropropylsiloxane, ZnO and TiO 2  and phenyltriethoxysilane and trifluoropropyltrimethoxysilane

Title: A method of neutralizing organic sulphonic acids and acid sulphates
Inventor: SUNDIEN GUNNAR OLOF
IPC: C07C303/44
Filed: 1948-07-23
Abstract: Organic liquid sulphonic acids or acid sulphates or crude mixtures containing these substances together with excesses of sulphonating agent are neutralized by bringing the liquid p  sulphonic material to an atomized state and contacting it with a gaseous or vaporized neutralizing agent such as ammonia or an amine, for example pyridine or piperidine.  The method is especially applicable to the neutralization of surface-active materials such as the higher acid alkyl sulphates R-OSO2OH and sulphonated mono-glycerides RCOOCH2CHOH CH2-OSO2OH, where R is a saturated or unsaturated alkyl group of preferably at least 9 carbon atoms.  The neutralization may be effected in an atomization drying plant. Neutralization is substantially instantaneous when particle size is of the same order as that used in atomization drying of solutions.  The heat of neutralization may be removed by supplying the gaseous neutralizing agent in large excess or in admixture with an inert gas, and part may be removed by introducing the neutralizing agent in liquid form and allowing it to evaporate. The neutralized products are obtained as dry powders.  In examples: (1) a mixture of coconut oil and glycerine is sulphonated with 13 per cent oleum and the product is atomized in the drying zone of an atomizing drier plant by a fast rotating disc and a gaseous mixture of ammonia and air is circulated through the drier and a cooler; an amount of ammonia equivalent to that used up in the neutralizing is also introduced, the supply being regulated by the pressure in the drying chamber, (2) as in (1) the ammonia however, being expanded into the chamber from a container of liquid ammonia via an expansion valve to a heat-exchange device, through which the circulating mixture of air and ammonia passes to be cooled, and thence to the reaction zone, the valve being controlled by the pressure in the chamber; (3) as in (1) using piperidine as neutralizing agent, it being supplied in liquid form to a scrubber in series with the said cooler and evaporating from the scrubber packing to be absorbed by and cool the gas mixture circulating through the plant.

In a thermostatically controlled valve, e.g. for dwelling house heating circuits, the flow between inlet 3 and outlet 4 is valved by an annular closure element 19 which is slidingly urged towards a seat 14 along a spindle 9 against a spring 20, upon expansion of a stack of thermostatic bi-metallic plates carried by the spindle which dome out in pairs, the setting of the valve being adjustable by an external control knob 10 in screwed or sliding engagement with the valve housing cover 2 and whereby a throttling effect is obtained by the end 11 of spindle 9 and whereby closure may also be effected by the engagement thereof with seat 14. The valve may also be applied in cooling rate limiting devices using a temperature responsive device which expands upon cooling. The valve seat 14 is preferably of stainless steel which may be moulded into the valve housing 1 produced from a non-ferrous metal, e.g. corrosion resistant aluminium alloy, by a pressure moulding or hot-pressing process. The connection pipes 3 and 4 may be cast with the housing 1 or be moulded-in and the movable inner parts of the valve consist of stainless steel. Air venting may be obtained via a vent bore (not shown) closed by a threaded pin with a vent channel. The narrow sealing surface 18 of the closure 17 minimizes pressure effects upon opening of the valve.
